HEELING, NAILING, AND FINISHING JACK.

SPECIFICATION forming part of Letters Patent No. 396,076, dated January15, 1889.

Application filed June 25, 1888. Serial No. 278,166. (No model.)

To aZZ whom, it may concern.-

Be it known that I. GEORGE DOR'WART, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inHeeling, Nailing, and Finishing Jacks, of which the following is aspecification.

My invention has relation to jacks for nailing, heeling, and finishingboots or shoes of the form shown, described, and claimed in LettersPatent of the United States granted to me on the 25th day of October,1887, No. 372,132; and it has for its object to cheapen and improve theconstruction of the jack and make it more durable and etficient, wherebythe operations of nailing, heeling, and finishing a boot or shoe arestill further expedited.

My invention accordingly consists of the combinations, constructions,and arrangements of parts, as hereinafter described in the specificationand pointed out in the claims, reference being had particularly to atoe-rest head or supporting-block having a springsupport in a standardrigidly secured to the rotating plate, to which is alsocorrespondingly-secured the heel-post for the last, where by both thestandards or supports for the heel and for the toe of the last arerigidly secured to the rotating plate and the toe-rest, and itssupportingblock has a direct up-and-down' vertical movement instead of aradial movement, an d a firmer foundation is provided for resisting theshocks incident to hammering or nailing than is provided by theconstruction shown in my aforesaid patent, and to so pivoting or hingingthe jack that it can be firmly or rigidly held in any angular position.

Reference being had to the accompanying drawings, Figure 1 is asectional elevation of a jack, showing my improvements. Fig. 2 is a planof the head or supporting block for the toe-rest. Fig. 3 is a horizontalsection, partly in plan, of the toe-rest supporting-block stem and thestandard therefor detached from the rotating plate and showing apreferable construction in cross-section of the standard and Fig. 4 is avertical section drawn to an enlarged scale through the hinged orpivotal connection for the jack, showing more plainly thespring-actuated locking-bar for holding the jack in its normal positionand the clutch mechanism for holding it in an angular position. Fig. 5isan elevation of same, looking in direction of arrow at, Fig. 4. Figs.6 and 7 are elevations showing the inner faces or sides of theclamping-plates to which the jack is hinged or pivoted; and Fig. 8 is anelevation, partly sectional, showing the lug on the jack, which isinserted between and pivoted to the clamping-plates, the same beingshown detached from the jack and the lockin g-bartherefor indicated insection.

A represents a bench, box, column, or other support for the jack, havinga treadle, B, provided with an upright rod or bar, I), passing upwardlythrough an opening, a, in the top a of bench or support A, in a mannersimilar to that shown and described in my aforesaid patent, orotherwise, asdesired.

O 0 represent, respectively, the lower and upper circular plates of thejack proper, which are preferably swiveled together in the followingdescribed economical way: The plate 0 has a central opening, 0,surrounding which, on its under side, is a shoulderor annular recess,0', for the reception of an edge flange, cl, of a tubular sleeve, D, inopening 0, as shown. The exterior of the upper end of sleeve D isthreaded, as shown at cl, to screw into a threaded opening, 0 in the topplate, 0, and thus loosely secure or swivel said plates together toadmit of rotating the top plate, 0, on the lower plate, (7.

The :t'oregoing-described swivel-connection is such that no part of thesleeve D depends below the bottom of the lower plate, 0, and hence thelatter can be placed upon a bench or other support without necessitatinga specially-formed recess or enlargement at the top of the opening a insaid bench or support, as

is required with the form or swivel shown and described in my aforesaidpatent. Furthermore, the said form of swivel herein illustrated firmlyholds said plates together and admits of easy removal of the top plate,0', from the lower plate, 0, and corresponding replacement for repairsor other purposes.

2 seearte post is provided with an adjustable top pin, 6, for insertioninto the top of the heel part of the last, and with a set-screw, c, forsaid pin,as set forth in nrva'tforesaid patent. The toe-rest F isadjustable in a head or suptnn'ting block, t, which may be of anysuitable construction; but I prefer to made it as hereinafter to bedescribed. This headblock (t has a stem, g, which is inserted in thebore 71 of a tubular standard, ll, in which is a spiral or other spring,71, upon which said stem rests, so as to have a spring bearing instandard or column ll. The spring ll has an upward action to normallykeep the ln' ad-block G and toe-rest l elevated or to move themupwardly,

The standard It is rigidly secured to or east on the plate and isn'ovided with vertieally-arranged slots 71 through which passes across-bar or studs, g, secured to the head or supporting-l)lock stem g.The ends of bar or studs 9' are preferably provided with rollers g whichproject: laterally b(, vond the standard II, as shown more plainly inlaig. 3. The studs or bar g and 'the upper end of slots 7: limit theupward movenn'ent of stem 5 and consequently of the head (i and toerestF. The upper side of the head-bl wk (l is provided with aseries of.transverse grooves or recesses, G, of the corrugated communicating formshown in Fig. 2, or they may otherwise be ('(mtigured and arranged, asdesired, to eontorm to the shank end fol? the toe-rest F, so that saidend f may be inserted into any one ol? the recesses G to admit olfadjustably attaching and detaching the toerest- F to the head G, asdesired.

To give the proper inclination to the toeresl ll as it is adjusted inthe head (l, the lat: ter isol' a curved tin-segmental form, as shown inFig. l, and the recesses Gtherein conl'ln'm to the ctmliguration ol' theblock.

llpon one side of standard It is :rlug, 71", having a stop'piece or end,71 ,and to this lug 71 is pivoted a lever, K, the upper part of which isbifurcated to embrace the standard 11, so as to admit oi each leg or endot. the bil'ureation impinging against oneol' the rollers on studs orbar 5 T0 the lower end, 7a, of lever K is pivoted a block, I, having,1)l.'6l'. l;ll.)l a concave or recessed under side, 1, into which entersthe top of treadle-bar (1, as shown in l ig. l, to be in line with saidblock I and lever 11 when in their normal positions, so that when therod 1) is elevated by depressing the treadle ll the block I isC-(ill'GSPOlllllllg'ly moved to oscillate lever K in the direction ofarrow y, whereupon. its lever ends moving against the stud or barrollers on the head-stem g, dc press the latter and. the toe-rest. F, asindicated by dotted lines, Fig. l. As soon as the pressure on thet-readle is rennived, the reaction of spring 7t returns the lever ll,head G, and toe-rest F to their normal positions. The plate (J isprovided at its periphery, on one i side of the same, with a lug orbracket, 9)), terminating in a disk-shaped end, on, having a centralaperture, m a peripheral recess or slot, in, and on one or both sides alug, /11 located, preferably, between the opening m and the taco ol' thedisk. This disk is insorted between two upright plates or leaves, N N,cast or secured to a base-plate, n, so that they will not be connectedone with the other. 'lhebase-plate a is suitably and firmly fastened tothe top of the bench or support A, as indicated.

'.l"heplatcNhas a central round aperture, )1, and. the plate N" anangularcentral aperture, nfleomm unicating with the l all? or of a tuln1 lar projectiml, n, on the inner side of said plate, which tubularprojection '11" forms a bearing for the end or disk in ol plate as moreplainly shown in Fig. 4'.

Upon the inner sides ol the plates N N are preljerabl vvertically-loeated. lugs 11? 01", and at: or near the bottom olf plate Nis an opening, n, registering with theslot m in the periphery ol? diskend '11:. into or through tjheopening a and slot at" passes a bar, 1,having an aetuatirig-spring, p, an end bearing-,pi in the base-plate n,and a handle or tlnnnb-piece, p". The action of spring p is to normallymove the harp into the slot in to lock thediskend m and plate andconsequently the plate and lixtures thereon, in their normal position,or as shown in Fig. '1.

Through the central openings, n 11*, olf plates N N passes a bolt, 1,having an angle lar part, "r, correspoinling to the angular opening n'in plate X, and being provided with a thumb-nut, r recessed, as shown atr", in its rear side for the reception ot a spiral spring, r, forprevent ingthe thumb-nut-working loose by the vibrations incident topegging or linishing ot' the boot or shoe, and also to exert a pressurebetween the nut and the plate N l'or clamping purposes, about to bedescribed.

From the foregoing it will be noted that the plate or its disk end m ispivoted upon the tubular bearing n of plate N. ("onsequently when thethumb-nut r is unscrewed or loosened and the bar withdrawn from the disk-end slot on the jack can be raised to any angularposition desireduntil itslimitot' motion is reached, which happens when thelugs 1/1. onthe disk end n! abut against the vertical lugs a on the inner sides ofthe plates N N", which lugs llHI'tl UI'O are stops for limiting themovement of thejack on its pivotal or hinged connection.

The jack is lirmly locked in the angular position desired by turning thethumb-nut r until the plates N l\" clamp or bind against the sides olthe disk end m, said clamping by the turning of tho thumb-nut being assisted by the pressure of the spring r.

It" desired, a washer, .9, may be inserted between plate L\' and the notw to avoid wear of said plate.

A jack constructed as above described can be applied to any bench orsupport, and is easily and expeditiously changed from its normal to anangular position, and when clamped in the last-named position it isfirmly held so that the boot or shoe may be hammered or otherwiseoperated upon without jarring or straining the parts of the jack orloosening the effectiveness of its clamping engagement. \Vhen the jackis raised to an angular position, the normal position of lever K ismaintained by the tail or stop piece If of lug 71. which prevents amovement of the lever K away from the standard H, and as the block Z ispivoted to the lever K it always swings into its .normal position whenthe jack is lowered.

If desired, guides 6 may be formed on the stem g of head G, which guidesenter vertical ways or slots l in the standard II, as indicated in Fig.3, to give a firmer bearing to the stem 9 in the standard and avoidstrain on the studs or bar y when the spring 7L2 acts to move thetoe-rest F into contact with the last to clamp it upon the post-pin e.As the clamping of the last to the post-pin e is effected by a directupward or vertical move ment of the toe-rest F, a corresponding movementin a reverse direction instantly lowers the toe-rest from the last to atonce release the latter, whereas in my aforesaid patent in releasing thelast .it is further clamped to the heel-post by the radial movement ofthe toerest against the last before leaving the same.
